Retry error handling in Adobe Workfront Fusion

In some cases it is useful to re-execute a failing module if there is a chance that the reason for the failure might pass over time.

Workarounds to the Retry error handling directive

Adobe Workfront Fusion currently does not offer the Retry error handling directive, though two workarounds can be employed to mimic its functionality. For more information, see Directives for error handling in Adobe Workfront Fusion.

Use the Break directive

  1. In the The scenario settings panel in Adobe Workfront Fusion, enable the Allow storing of Incomplete Executions option.

  2. Attach an error handler route to the module, as described in Error handling in Adobe Workfront Fusion.

  3. Link the Break directive to the error handler route (see Directives for error handling in Adobe Workfront Fusion) and configure it.

Drawbacks

  • The minimum retry interval is one minute.
  • If the module is processing multiple bundles and the processing of a bundle fails, the partial execution (only the bundle that caused the error) is moved to the View and resolve incomplete executions in Adobe Workfront Fusion folder and scheduled for retries according to the Break directive settings. However, the current execution continues and the module continues to process the subsequent bundles. At least you can enable the “Sequential processing” option in the Scenario settings to prevent the scenario from executing again until the execution stored in the the Incomplete executions folder has been successfully resolved.

Use the Repeater module

  1. Employ the Repeater module and set its Repeats field to the maximum number of attempts.

  2. Link the potentially failing module to the Repeater module.

  3. Attach an error handler route to this module (see Error handling in Adobe Workfront Fusion).

  4. Link the Tools > Sleep module to the error handler route and set its Delay field to the number of seconds between the attempts.

  5. Link the Ignore directive after the Tools > Sleep module (see Directives for error handling in Adobe Workfront Fusion).

  6. Link the Tools > Set variable module after the the potentially failing module and configure it to store the module’s result in a variable named, for example, Result.

  7. Link the Array aggregator module after the Tools > Set variable and choose the Repeater module in its Source Module field.

  8. Link the Tools > Get variable module to the Array aggregator module and configure it to obtain the value of the Result variable.

  9. Insert the Tools > Get variable module between the Repeater module and the potentially failing module and configure it obtain the value of the Result variable.

  10. Insert a filter between this Tools > Get variable module and the potentially failing module to continue only if the Result variable does not exist.

INFO

Example: Here is a sample scenario where the HTTP > Make a request module represents the potentially failing module:

If the result of the potentially failing module is too complex to be stored in a simple variable, you may employ a data store to store/retrieve the result. The data store would contain just one record. The record’s key can be, for example, Result.

For more information on data stores, see Data Stores in Adobe Workfront Fusion

Drawback

This workaround might appear a bit too complex, and is also more demanding in terms of operations.
